I am attempting to plot some data in a matrix using the surf command. Every nonzero elements happens to be padded by zero elements (i.e. the elements and are zero for every nonzero . I'd like to plot a surface of the nonzero elements only, but I have tried a number of things and have not been able to figure out how to exclude the zero elements. For instance, I tried something like
but this method ignores all patches contiaining the zero element points and, due to the nature of my matrix, all surface patches are ignored.
Does anyone know how to request that matlab simply ignore zero elements in generating a surface plot?
